A method for performing gain estimation and imbalance compensation by combining IQ Imbalance Compensation and AGC in OFDM Systems

摘要

PURPOSE: By eliminating the function of being overlapped convention the IQ unbalanced compensation of the OFDM system and bond design method of AGC highly integrate the terminal. CONSTITUTION: The respective presumed amplitude benefit is compensated about the signal of newly inputted I / Q-channel(250). The digital transform process operates at each channel(260). The amplitude and phase are presumed through the result of the digital transform process(270). A presumed result as described above is delivered to the input of the first step, the phase compensation process operates(280).
